Identifying High-Quality Quartz for Sensor Fabrication through Infrared Spectroscopic Analysis of Metamorphic (Granite)rocks

Abstract

Abstract This research underscores the economic growth driven by the quality of quartz and its importance in national development, with a particular focus on India and the mineral-rich terrain of Tamil Nadu. The study explores various analytical methods employed for mineral identification, emphasizing meticulous procedures for spectrum recording and precautionary measures. Findings are interpreted against existing literature, highlighting crucial parameters such as crystallinity index, absorbance, and extinction coefficient. The infrared analysis of rocks from different regions of Tamil Nadu reveals a mineral profile featuring feldspar, garnet, chlorite, and ubiquitous quartz. Quartz, consistently present in all samples, is scrutinized through extinction coefficient comparisons. Keelaiyur stands out with the highest extinction coefficient, indicating superior quartz abundance and heightened crystallinity among the samples. Highly quality Quartz are abundant in Kellaiyur, Madurai District. These quartz are used to fabricate high quality quartz based sensors. Quartz-based sensors are high-quality due to their piezoelectric properties, stability, sensitivity, and precise fabrication techniques, ensuring reliable performance. This research sheds light on the geological wealth of Tamil Nadu, emphasizing the vital role of quartz and other minerals in economic development.Keywords:Rocks and Minerals, Quartz, infrared-based identification, crystallinity index, absorbance, extinction coefficient.
